Description

Technical Field

[0001] This utility model relates to the field of forging technology, specifically a high-strength forging platform for forging. Background Technology

[0002] Forging is a processing method that uses forging machinery to apply pressure to metal billets, causing them to undergo plastic deformation to obtain forgings with certain mechanical properties, shapes, and dimensions. During the forging process, a forging platform is usually used for support, but a typical forging platform is fixed and its height cannot be adjusted.

[0003] A search revealed a high-strength forging platform for forging with application number 202222573349.7. This device uses a second hydraulic cylinder to move an adjusting block, causing a moving column to slide within a fixed cylinder, thus adjusting the height of the worktable. Simultaneously, the area beneath the worktable remains non-hollow, ensuring high strength and resistance to breakage. However, in actual forging, because the adjusting block is tilted, the impact force generated by the hammer, after being transmitted to the adjusting block via the moving column, is partially dissipated by the base plate, while the remaining force is transmitted to the piston rod of the second hydraulic cylinder, creating an instantaneous dynamic load far exceeding normal operating conditions. The piston rod of the second hydraulic cylinder may be subjected to alternating stress, leading to material fatigue. Furthermore, the oil pressure in the hydraulic system may momentarily exceed the set pressure, triggering frequent opening and closing of the safety valve, which can easily damage valve components or pump units over time. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a high-strength forging platform for forging, so as to solve the technical problems in the background art mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength forging platform for forging, comprising a base, a hydraulic cylinder connected to one side of the top of the base via a mounting plate, a connecting seat connected to the output end of the hydraulic cylinder, a fixed cylinder and an adjusting seat connected in the middle of the top of the base, with the adjusting seat penetrating the fixed cylinder, a forging press installed inside the fixed cylinder, a limit frame connected to one side of the adjusting seat, a support plate placed inside the limit frame, a pulley connected inside the support plate via a rotating rod, a spring installed inside the base, and a locking block connected to the top of the spring.

[0006] Furthermore, a forging hammer is mounted on the other side of the base via a mounting bracket.

[0007] By adopting the above technical solution, when it is necessary to adjust the height of the forging press, the operator starts the hydraulic cylinder. The output end of the hydraulic cylinder pushes the adjusting seat to move through the connecting seat. With the cooperation of the fixed cylinder, the adjusting seat pushes the forging press, pushing the forging press out a certain distance, thereby completing the height adjustment of the forging press. In this way, the distance between the forging hammer and the forging press is shortened, which makes it convenient to forge workpieces of different sizes.

[0008] Furthermore, a groove is provided in the middle of the top of the base, and the adjusting seat is slidably connected to the groove.

[0009] By adopting the above technical solution, the adjusting seat slides inside the groove under the drive of the hydraulic cylinder output end. The groove limits and guides the adjusting seat, thereby preventing the adjusting seat from deviating when sliding and affecting the practicality of the device.

[0010] Furthermore, there are four sets of springs, and the four sets of springs are distributed at equal intervals.

[0011] By adopting the above technical solution, the length of each locking block plus the length of the support plate is the distance that the adjusting seat adjusts the forging table once. During the movement of the adjusting seat, the adjusting seat releases the limiting position on the locking block. Under the action of the spring force, the locking block is pushed out a certain distance in sequence. Through the cooperation of the locking block and the support plate, the adjusting seat is fixed, thereby fixing the position of the forging table after adjustment.

[0012] Furthermore, the support plate is movably connected to the limiting frame.

[0013] By adopting the above technical solution, when the adjustment is completed, the hydraulic cylinder is activated, which drives the slide table to move backward a certain distance. With the cooperation of the limit frame, the pulley drives the support plate to move along the guide rail. At the same time, the support plate slides down inside the limit frame. When the pulley is at the bottom of the guide rail, the support plate is locked between the locking block and the adjustment seat. At the same time, one side of the slide table is disengaged from the adjustment seat. The support plate and the locking block work together to deflect the oblique impact force generated during forging and guide the impact force to the base, so as to avoid the impact force affecting the output end of the hydraulic cylinder.

[0014] Furthermore, the connecting seat has a guide rail inside, and the longitudinal section of the guide rail is V-shaped.

[0015] By adopting the above technical solution, when the slide moves towards the forging table, the support plate is located on the left side of the slide. Driven by the output end of the hydraulic cylinder, one side of the slide's interior abuts against the support plate, pushing the support plate to move the adjusting seat. After the adjustment is completed, the output end of the hydraulic cylinder drives the slide to retract. At this time, the pulley moves along the guide rail to the lowest point of the guide rail, thereby driving the support plate to move down and engage between the locking block and the adjusting seat. When it is necessary to reset the adjusting seat, the output end of the hydraulic cylinder continues to retract, and the pulley moves along the guide rail to the highest point on the other side of the guide rail. During the movement, the support plate moves up. At this time, the support plate is located on the right side of the slide and abuts against the other side of the slide's interior, thereby pulling the support plate to move the adjusting seat and reset it.

[0016] Furthermore, the adjustment seat is inclined on both the lower side and the upper side of the locking block.

[0017] By adopting the above technical solution, when the adjusting seat is reset, the adjusting seat contacts the locking block during the movement and squeezes the locking block, thereby causing the locking block to move down and compress the spring. By tilting the setting, the adjusting seat can better squeeze the locking block.

[0018] Furthermore, a protective cover is installed between the mounting plate and the fixing cylinder, and observation windows are provided on both sides of the protective cover.

[0019] By adopting the above technical solution, the protective cover is installed on the mounting plate and the fixed cylinder by bolts. The protective cover blocks the oxide slag, preventing the oxide slag from falling directly into the groove and affecting the sliding of the locking block and the adjusting seat. The observation window allows the staff to observe the work.

[0020] In summary, the present invention has the following main advantages:

[0021] 1. This utility model is equipped with pulleys, guide rails and support plates. When the hydraulic cylinder output end is driven and cooperates with the limit frame, the pulley moves along the guide rail, causing the support plate to engage with the gap between the locking block and the adjusting seat. Thus, after the hydraulic cylinder output end loses contact with the adjusting seat, the locking block and the support plate cooperate to support the adjusting block, preventing the impact force generated during forging from being transmitted obliquely, causing the adjusting seat to move, and thus avoiding the possibility of the hydraulic cylinder output end being impacted by the impact force.

[0022] 2. This utility model is equipped with springs and locking blocks. The length of each locking block plus the length of the support plate is the distance that the adjusting seat adjusts the forging table once. During the movement of the adjusting seat, the adjusting seat releases the limiting position on the locking block. Under the action of the spring force, the locking block is pushed out a certain distance in sequence. The support plate and the locking block cooperate to unload the oblique impact force generated during forging, thereby transmitting the impact force to the base. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of this utility model will be described below based on its overall structure.

[0031] Example 1: A high-strength forging platform for forging, such as Figures 1-5 As shown, the system includes a base 1. A hydraulic cylinder 3 is connected to one side of the top of the base 1 via a mounting plate 2. A connecting seat 4 is connected to the output end of the hydraulic cylinder 3. A fixed cylinder 11 and an adjusting seat 7 are connected to the middle of the top of the base 1, and the adjusting seat 7 passes through the fixed cylinder 11. A forging table 12 is installed inside the fixed cylinder 11. A limit frame 8 is connected to one side of the adjusting seat 7. A support plate 9 is placed inside the limit frame 8. A pulley 10 is connected to the support plate 9 via a rotating rod. A spring 13 is installed inside the base 1. A locking block 14 is connected to the top of the spring 13. A forging hammer 15 is installed on the other side of the base 1 via a mounting frame. When the height of the forging table 12 needs to be adjusted, the operator starts the hydraulic cylinder 3. The output end of the hydraulic cylinder 3 pushes the adjusting seat 7 to move through the connecting seat 4. With the cooperation of the fixed cylinder 11, the adjusting seat 7 pushes the forging table 12, pushing the forging table 12 out a certain distance, thereby completing the height adjustment of the forging table 12. By shortening the distance between the forging hammer and the forging table 12 in the above way, it is convenient to forge workpieces of different sizes.

[0032] See Figure 1 , Figure 3and Figure 5 In the above embodiment, a groove 6 is provided in the middle of the top of the base 1, and the adjusting seat 7 is slidably connected to the groove 6. Driven by the output end of the hydraulic cylinder 3, the adjusting seat 7 slides inside the groove 6. The groove 6 limits and guides the adjusting seat 7, thereby preventing the adjusting seat 7 from deviating when sliding, which would affect the practicality of the device.

[0033] See Figure 2 , Figure 3 and Figure 5 In the above embodiment, there are four sets of springs 13, and the four sets of springs 13 are equidistantly distributed. The length of each locking block 14 plus the length of the support plate 9 is the distance that the adjusting seat 7 adjusts the forging table 12 once. During the movement of the adjusting seat 7, the adjusting seat 7 releases the limiting of the locking block 14. Under the action of the spring force of the spring 13, the locking block 14 is pushed out a certain distance in sequence. The adjusting seat 7 is fixed by the cooperation of the locking block 14 and the support plate 9, thereby fixing the adjusted position of the forging table 12.

[0034] See Figure 3 and Figure 5 In the above embodiment, the support plate 9 is movably connected to the limiting frame 8. When the adjustment is completed, the hydraulic cylinder 3 is activated, causing it to move the slide table backward a certain distance. With the cooperation of the limiting frame 8, the pulley 10 causes the support plate 9 to move along the guide rail 5. At the same time, the support plate 9 slides down inside the limiting frame 8. When the pulley 10 is at the bottom of the guide rail 5, the support plate 9 is engaged between the locking block 14 and the adjusting seat 7. At the same time, one side of the slide table is disengaged from the adjusting seat 7. The support plate 9 and the locking block 14 work together to unload the oblique impact force generated during forging and guide the impact force to the base 1, so as to avoid the impact force affecting the output end of the hydraulic cylinder 3.

[0035] See Figure 2 , Figure 3 , Figure 4 and Figure 5 In the above embodiment, the connecting seat 4 is provided with a guide rail 5 inside, and the longitudinal section of the guide rail 5 is "V" shaped. When the slide moves towards the forging table 12, the support plate 9 is located on the left side of the slide. Driven by the output end of the hydraulic cylinder 3, one side of the slide abuts against the support plate 9, pushing the support plate 9 to move the adjusting seat 7. After the adjustment is completed, the output end of the hydraulic cylinder 3 drives the slide to retract. At this time, the pulley 10 moves along the guide rail 5 to the lowest point of the guide rail 5, thereby driving the support plate 9 to move down and lock into the locking block 14 and the adjusting seat 7. When it is necessary to reset the adjusting seat 7, the output end of the hydraulic cylinder 3 continues to retract, and the pulley 10 moves along the guide rail 5 to the highest point on the other side of the guide rail 5. During the movement, the support plate 9 moves up. At this time, the support plate 9 is located on the right side of the slide and abuts against the other side of the slide, thereby pulling the support plate 9 to move the adjusting seat 7 and reset it.

[0036] See Figure 2 , Figure 3and Figure 5 In the above embodiment, the lower side of the adjusting seat 7 and the upper side of the locking block 14 are both inclined. When the adjusting seat 7 is reset, the adjusting seat 7 contacts the locking block 14 during the movement and squeezes the locking block 14, thereby causing the locking block 14 to move down and compress the spring 13. By being inclined, the adjusting seat 7 can better squeeze the locking block 14.

[0037] Example 2: To avoid the oxide slag generated during forging falling into groove 6 and being difficult to clean, Example 2 is an improvement on Example 1. (See attached document.) Figure 1 A protective cover 16 is installed between the mounting plate 2 and the fixed cylinder 11, and observation windows are provided on both sides of the protective cover 16. The protective cover 16 is installed on the mounting plate 2 and the fixed cylinder 11 by bolts. The protective cover 16 blocks the oxide slag and prevents the oxide slag from falling directly into the groove 6 and affecting the sliding of the locking block 14 and the adjusting seat 7. The observation windows facilitate the observation by the staff.

[0038] The implementation principle of this utility model is as follows: When adjusting the height of the forging table 12, the output end of the hydraulic cylinder 3 drives the connecting seat 4 to move, so that one side of the connecting seat 4 pushes the adjusting seat 7 to move. With the cooperation of the fixed cylinder 11, the adjusting seat 7 pushes the forging table 12, pushing the forging table 12 out a certain distance, thus completing the height adjustment of the forging table 12. During the movement of the adjusting seat 7, the adjusting seat 7 releases the limit on the locking block 14. Under the action of the spring force of the spring 13, the locking block 14 moves up a certain distance. When the adjustment is completed, the hydraulic cylinder 3 is activated, which drives the slide table to move backward a certain distance, so that one side of the connecting seat 4 is disengaged from the adjusting seat 7. At this time, under the action of gravity, the pulley 10 drives the support plate 9 to move along the guide rail 5, so that the support plate 9 slides down a certain distance. When the pulley 10 is at the bottom of the guide rail 5, the support plate 9 is just locked between the locking block 14 and the adjusting seat 7 and contacts the base 1, thereby avoiding the impact force generated during forging from affecting the output end of the hydraulic cylinder 3.
